Hubby has ADHD & Is Addicted To Marijuana

I'm just learning the effects of having ADHD and the smoking of marijuana. My husband has been smoking since he was 13. He smoked more when he was single, now we have boundaries in place, which he sometimes breaks, and he only smokes three times a month, rather than every weekend. 

He was having trouble sleeping at night and suggested marijuana gummies, which I said yes to not knowing the effects it had of a person that has ADHD. I have them and don't give them to him unless I feel he needs it but I hate treating him like a child.

I suggested he try listing to crickets at night as he love nature, that has seem to work for the time being. 

I just want to know if there is anyone else out there going through the same time.
